. cut-01f for internal combustion engines and has for its object to provide a device of this character which embodi'es'novel features of construction whereby it can be readily applied to any conventional construction of automobile and will provide a lock controlled means for cutting 05 the supply of gasolene to the carbureter so that the car can be left standing Without danger of being stolen or used by unauthorized persons. 20'

' Further objects of the invention are to provide a device of this-character which is simple and inexpensive in its construction, which will automatically cut off the flow of gasolene to the carbureterif any effort is made to tamperwith the same, which can be easily and quickly locked in either an open or a closed position, and which will render it impossible for the car-to be' used or stolen when the cut-off is locked in operative positi'on.--

With. these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear asthe description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention, reference isto be-had to the following description and accompanying drawing, in which v r V Figure 1 is a transverse sectional View through a gasolene tank provided with a cut-off constructed in accordance with the invention, portions of the seat under which the tank is mounted also being shown.

Corresponding and like parts are referred to in the following description and indi- .r cated 1n all the views offlthe drawing by the same reference characters;

Specifically describing the present embodiment of the invent on, the numeral 1 designates the gasolene tank which may be of any conventional constructlon and which is shown asmounted in the usual manner under a "seat 2.- A sediment bulb 3 is provided-at the botto'm pf the tank land .av

gaso'l'enesupply pipe l communicates with one sideof the sediment bulb, said'supply pipe serving to convey gasolene from the tank .tothe carbureter. The usual drain ment "bulb. V A valve 6 is provided forclosing theend of the supply pipe 1, said valve being carcock 5 is applied to the bottom of the sediried' an arm 7 which is. pivoted at 8 upon a pair of ears projecting inwardly from one side of the sediment bulb. A rearwardly projecting lever 9 is rigidly connected with the arm-7 at the pivot endthereof and constitutes means for. swinging the arm to move the valve toward or away from its seat. The free end ofthe lever 9 'is loosely connected by an upright link 10 to a slidell which is mounted upon an upright guide rod 12 projecting from the bottom of, the

sediment'bulb; 'A' coil spring 13 surrounds the guide rod 12 and is interposedbetween j the bottom of the sediim'ent "bulb and the l slide 11 so as to norma y" move the slide upwardly and swingthe valve 6 "into a closed position, thereby cutting OK the flow} of gasolene'a'nd rendering it impossible tostart the engine. The upper end of the guide rod 12-tern1inatesinahead 14: which is loosely receivedwithin acage 15 at the lower end of an upright push rod '16, the upper end of the saidpush rod being provided with, a socket 17 which. loosely receives the: lower endof'a plunger 18. Theupper end of; the plunger 1'8 extends through asuitable packing box 19 at the top of the tank 1 andin the present instance the lower endof the plunger is offset laterally since the socket .17 and packing box 19 are slightly out of alinement with each other. j

The upper extremity of the pl'unger lS has a pin and slot connection with one arm of an upright bell crank lever 21 which is 'pivotal'ly mounted upon a bracket 22 prospring'13 and open the cut-0E valve.

jecting from the top of the tank 1; The opposite arm ofthe bell crank lever 21 is connected to a horizontally disposed locking slide 23 which passes through suitable guide opening in the front 2 ofthe seat 2. Vv ith this construction it will be obvious that by sliding the locking rod 23 back and forth motion can be transmitted through the bell crank lever 21 to the plunger 18 so as to reciprocate the latter up and down. When the plunger is pushed down the cage 15 at the lower end of the push rod 16 engages the slide'll and moves the same against the action of the spring 13 so as to open the cutoff valve 6. On the other hand, when the plunger 18 is moved upwardly the action of the spring 13 will also move the slide 11 and push rod 16 upwardly so as to result in closing the cut-ofi valve 6.

The forward end of the locking rod 23 is provided with a pair of spaced notches 24: and 25 adapted to be engaged by the tongue 26 of a suitable cabinet clock 27 which is mounted in the front 2 of the seat. l/Vhen the locking rod 23 is pulled outwardly and the tongue 26 of the lock caused to engage the notch 24 thereof, as indicated by Fig. 1, the cut-off valve 6 is held in a closed position by means of the spring 13, thereby preventing gasolene from flowing through the supply pipe 4: and rendering it impossible for the engine to be started. When the cutoff is thus locked in a closed position the car may he left standing with absolutely no danger of being stolen or used by an unauthorized person. When it is desired to use the car, thelocking rod 23 is pushed inwardly and the tongue 26 of the lock caused toengage the outer notch 25 of the locking rod. The plunger 18 and push rod 16 are thereby forced downwardly so as to move the slide 11 against the action of the Gasolene can then flow freely through the supply pipe so that the engine can be started and the car used in the usual manner.

Any suitable form of cabinet lock can be utilized for engaging the notches of the locking rod 23 to hold the cut-off securely in either an open or a closed position, and when leaving the car the operator can very quickly lock the cut-off in a closed position so as to render it impossible for any person to start the engine and use the car. Attention is also directed to the fact that the plunger 18 fits loosely within the socket 17 of the push rod 16 so that should any effort be made to tamper withthe cut-ofi mechanism by destroying the portions thereof mounted upon the eXterior of thetank and withdrawing the plunger 18, the only result will be to disengage the plunger from the push rod so that the latter will fall over to one side and the cut-off valve will be closed by the action of the spring 13, This I again.

would leave the car dead until after the gasolene was drawn off and the parts of the cut-off mechanism properly connected up It will thus be obvious that by formingthe connecting link between the bell oranklever 21 and the slide 11 in two parts as illustrated upon the drawing effective provisionis made against successful tampering with the cu't-ofi mechanism by any perattempting to steal or make unauthorized use of the car.
